Sweet potato Vitamin A research wins World Food Prize
Four scientists have been awarded the 2016 World Food Prize for enriching sweet potatoes, which resulted in health benefits for millions of people.
They won the prize for "the single most example of biofortification", resulting in Vitamin A-boosted crops.
Since 1986, the World Food Prize aims to recognise efforts to increase the quality and quantity of available food.
The researchers will receive their US $250,000 (£203,000) prize at a ceremony in Iowa, US, on Thursday.
Three of the 2016 laureates - Drs Maria Andrade, Robert Mwanga and Jan Low from the CGIAR International Potato Center - have been recognised for their work developing the vitamin-enriched orange-fleshed sweet potato (OFSP).
The fourth winner, Dr Howard Bouis who founded HarvestPlus at the International Food Policy Research Institute, has been honoured for his work over 25 years to ensure biofortification was developed into an international plant breeding strategy across more than 40 countries.
